Specification of Letters Patent.

Patented Apr. 11, 1916.

Application at August 23, 191i. Serial no. 645,633;

To all whom it may concern:

Be it known that I, ALBERT T. WEISS, of Rochester, in the county ofLMonroe and State of New York, have invented certain new and useful Improvements in Extension-Drawers; and I do hereby declare the following to be a full, clear, and exact de-. scription of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the referencenumerals marked thereon.

My present invention relates to furniture and more particularly to furniture drawers and hasfor its object to provide an improved means of the extension type for supporting a' drawer in its open position.

A further object of the invention is to provide for the convenient and ready removal of the drawer and its complete detachment from its support, when desired, and the improvements are further directed to simplicity of parts and economy in manufacture. l I

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a side elevation of a drawer and its casing constructed in accordance with and illustrating one embodiment of my invention'yFig. 2 is a similar view with the-drawer ready to be completely detached from its cas1ng; Fig.-

3 is a horizontal section taken substantially on the line 3-3 of Fig. 2, showing in plan view the front portion of the drawer and its supporting parts, and Fig. 4 is a detailed perspective view of the forward end of one of the extension supports.

, Similar reference numerals throughout the several figures indicate similar parts.

The'casing or'cabinet '1 as shown in'the present embodiment, is of a skeleton strucf ture embodying front, intermediate and rear vertical rails 2, 3 and 4 and the whole forms a chamber in which operates the drawer 5. As the drawer is hung in the same manner on each side a description of one of these sets of hanging devices will sufiice for both.

The extension support: 6 is arranged between the side of the drawerand the side wall of the casing and slides 1n and out 1n a guideway formed b tween upper and lower cleats 7 and 8 secure to the rails 2, 3 and 4. The lower side of the upper cleat 7 the upper side of the lower cleat 8 and both the upper and lower sides of the extension support 6 are provided with grooves 9 forming tracks that receive and retain anti-friction rollers 10 which I prefer not to mount on fixed axes but allow to roll freely. It will be understood that the extension support may thus be moved a limited distance to project forwardly from the drawer chamber and to react againstthe cleats 7 and 8, as' is usual in such devices.

The forward end of the extension support is bifurcated to form a horizontal guideway -11, the forward end of which is open at the front end ofthe support, while.

the rear end is closed and provided with a suitable buffer 12. Traveling inthis guide- I lower sides of the guidew-ayj 11. Thesejg" tracks 9 and 16 together with their respec i I tive rollers prevent" the lateral disengage- .ment of the support 6 from the casing and of thedrawer from the support. l

The forward end of the guidewa 11 is normally closed by an abutment 1 preferably carrying a buffer 18 that enters between the tracks of the guideway, which abutment is in the form of a yoke, th e hori-.

zontal arms 19 of which are pivoted at 20 to the extension 6 on opposite sides of the guideway 11 or to the respectiveseparated parts thereof left by the bifurcation, while the intermediate portion carrying the beacross the end of the. extension and spans member 13' on the drawer, or moreparticularly its forward roller 15.

'- In the ordinary operation of the device,

the guideway in the path of the supporting when the drawer is pulled forwardly the extension 6 moves forwardly on its own guideway for a limited distance defined by the arriyal of the anti-friction rollers 10 at the 'ends of their tracks 9 so that its forward end projects a considerable distance from 95 forementioned buffer 18 extends vertically v the buffer 12 at the rear end of the extension support to halt its own movement and also to insure the complete inward move-- ment of the extension.

When it is desired to remove the drawer entirely from the cabinet or casing and detach it from the supports the abutment 17 is simply swung laterally to the position shown in Figs. 2 and 3 at which it lies at the sideof the guideway and is no longer in alinement wlth or in position to close the open forward end of the latter. It is therefore only necessary to continue the forward movement of the drawer to cause the supporting projection 13 thereon, and its rollers, toissue from the guideway 11 and the drawer is then free. In reinserting the drawer, serted in the open end of the guideway 11 with the parts inthe same position of Figs. 2 and 3 and, after bringing the other roller 14 in horizontal alinement therewith shove the drawer into its position on the extension support 6. As it is subsequently pushed tomatically effected into thechamber, the roller 15 will engage the bufier 12; at the inner end of the guideway 11 and cause the extension 6 to. move to its extreme closed position also. In\ so doing, is then in its lateral position, is engaged by a stop, furnished in thepresent instance by the front rail 2 of the cabinet, as clearly shown in Fig.' 3, and caused: thereby to swing forwardly to its operative position at the front end of the extension and to again close the open end of the guideway 11, as before. The readjustment of the parts whereby the drawer is locked against disengagement from the supports is thus aumerely by continuing the closing movement of the drawer after its supporting projection is once inserted in its guideway.

A device constructed in accordance with my invention. will be found to ofler great advantages particularly when it is desired to detach or replace drawers that have considerable weight or are heavily laden, the necessary manipulation of the drawer consisting merely in raising it vertically to the proper level and then thrusting it in a horizontal direction, while the end of the guidethe rear roller 15 may be easily m-' the yoke-shaped abutment 17, which way 11 in which the roller 15 must be initially inserted is at the same time in full view as well as is its cooperating part.

I claim as my invention.

1. The combination with a drawer and a support therefor, one of said parts being provided with a guideway arranged laterally of the drawer comprising upper and lower tracks and the other with a drawer supporting member traveling in the guideway as the drawer is operated, of a permanently attached but movable abutment at' one end of the guideway normally extending across the latter from one track to the other and secured on opposite sides'of both tracks to prevent the drawer supporting member from being withdrawn from the guideway, said abutment being movable while still connected to the guideway. to a position at one side of the latter to permit the removal of said drawer supporting member.

2. The combination with a drawer and a support therefor, one of said parts being provided with a guideway comprising upper. and lower tracks and the other with a supporting member traveling in the guideway as the drawer is operated, of a movable abutment at one end of the guideway embodying a yoke shaped member having its arms pivoted to the part on which the guideway is formed and its intermediate portion normally spanning theguideway to prevent the supporting member from being withdrawn from the latter, the abutment being adapted to be swung on its pivot to carry the said intermediate portion to one side of the guideway and permit the removal of the supporting member from the latter.

3. The combination with a drawer and an extension support therefor, the latter being bifurcated at one end to form a guideway .and the former being provided with a supporting member movable in the guideway as the drawer isoperated, of an abutment on the extension support embodying a yoke shaped member having its arms respectively pivoted on each side of the guideway and its intermediate portion adapted to swing laterally into and out of a position in which it closes the 'open end of the guideway against the withdrawal of the supporting member. I 4. The combination with a casing forming a drawer chamber and a drawer and an extension support therefor arranged laterally of the drawer operating therein, one of said last mentioned parts being provided with a guideway open at one end and the other with a drawer supporting member traveling in said way as the drawer is operated, of an abutment mounted on the part in which the guideway is formed and movable into and out of a position in which it closes the open end of the latterv against the withdrawal of the drawer supporting member therefrom, and a stop on the casing arranged tq engage the abutment and actuate it to such closed position automatically with the closing movement of the drawer.

5. The combination with a casing forming a drawer chamber and a drawer and an extension support therefor operating in the .chamber, the extension support being arport to normally close the end of the guide-- 15.

ranged between the drawer and casing and provided with a guideway open at the forward endthereof and the drawer being pro-' 'vided with a supporting projection traveling in the guideway as the drawer is operated, of an abutment pivoted to the extension supway against the withdrawal of the supporting projection on the drawer and movable laterally to permit such withdrawal and a stop on the casing arranged to cooperate with the abutment when in such lateral position and move it to closed position automatically as the extension support is thrust inwardly within the drawer chamber.

6. The combination with a casing forming a drawer chamber, a drawer operating thereon, an extension support for'the latter arranged between the' drawer and casing and the .open end of the guideway against the withdrawal of the supporting projection on the drawer, said abutment being arranged to be engaged by the wall of the chamber and moved to closed position automatically when I the drawer and its supporting extension are moved inwardly into the drawer chamber.
